Microsoft has never released a service pack for Windows98 SE. But I made a Service Pack for Windows98 SE users. It contains all Windows98 SE updates from WindowsUpdate site and more. 52 hot fixes. (All of them are from Microsoft's WindowsUpdate.) 256-color tray. (Some icons on the tray like WinAMP's icon will be shown better.) Better Defrag. (Faster. It is from Windows ME. However, It works properly on the Windows98 SE.) Better Notepad. (Same Notepad with more key bindings.) Optimized swap file usage. (Windows will not to use the swap file at all until all of the RAM is used.) Better WDM/USB support. (Most problems about WDM drivers and USB devices are solved.) Windows Scripting Host 5.6. (It is latest version of Scripting Host which also contains VBScript and JScript support.) Visual Basic 6.0 SP5 runtime library. (To run Visual Basic 6.0 programs.) Windows2000 color scheme. (You should select it from Control Panel-Display-Apperance.) A few performance tweaks.
